Use only one end of the cradle so you can get inside to buck the rivets for the top
edge of the spar.

Ouch! It's a tight fit for folks with normal sized hands. Wear a long sleeve sweatshirt
to protect your arms.

Turn the pressure down (30 lbs) so you don't beat up the curve of the skin where it
goes over the spar.

Here are a couple of mini bucking bars fabricated by RV4 builder and Minimax test
engineer Mark Spry that are invaluable for getting into tight spots.

I like to use the Scotchbrite wheel to dress the heads of the pulled rivets.
